EBI - External Bus Interface
Description
EBI External Bus Interface (EBI) Peripheral API.
This module contains functions to control the EBI peripheral of Silicon Labs 32-bit MCUs and SoCs. The EBI is used for accessing external parallel devices. The devices appear as part of the internal memory map of the MCU.
